AFAIK, there isn't a way for an ActivityPub Actor (such as a Person actor) to specify a list of Service actors associated with it.

...

For example, imagine that there is a Service actor that represents a way to make a video call to me.

And, for example, I have my Mastodon Person actor.

And, I want to let people know about it (and other Service actors associated with me).

How do I do that using AP, etc‽

...

#ActivityPub #ActivityStreams #AudioCall #Call #FediDev #Fediverse #VideoCall

Continuing to look for an alternative to "attachment" (for properly supporting an Actor specifying a list of CALL Service actors associated with it) —

Maybe a call specific custom top-level attribute would be useful.

Maybe something like:

"call": [
{
"rel":"callpub",
"href":"https://videocalls.example/users/joeblow"
}
]

Or even:

"call": [
"href":"https://videocalls.example/users/joeblow"
]

.

#ActivityPub #ActivityStreams #AudioCall #Call #FediDev #Fediverse #VideoCall

Although perhaps that is not much better than "attachment", if you just care about calls

So —

#ActivityPub #ActivityStreams #AudioCall #Call #FediDev #Fediverse #VideoCall

I think "endpoints" would also be a poor choice, too. Again, the semantics are wrong, or at least lacking.

So —

#ActivityPub #ActivityStreams #AudioCall #Call #FediDev #Fediverse #VideoCall

I think using "alsoKnownAs" or "sameAs" would be a poor choice. The semantics are wrong.

For example: a Service actor might represent my mobile phone (or software on it). My phone is not me. It is something I have.

So —

#ActivityPub #ActivityStreams #AudioCall #Call #FediDev #Fediverse #VideoCall

But, what about the non- fall-back situation where software could properly support this (when an Actor specifies a list of Service actors associated with it)‽

I think some might say, put the associated Service actors in "attachment". And, semantically I think that would work with ActivityPub, but — I have a very strong dislike with putting everything in "attachment" (and "tag"). It makes parsing difficult.

So —

#ActivityPub #ActivityStreams #AudioCall #Call #FediDev #Fediverse #VideoCall
